Default keyboard shortcuts for Ghostty terminal emulator. Platform-specific differences are noted where applicable.

Just a somewhat chaotic list of Proxmox VE related tips/notes.

Please note that unless you see a shebang (#!/...) these code blocks are usually meant to be copy & pasted directly into the shell. Some of the steps will not work if you run part of them in a script and copy paste other ones as they rely on variables set before.
The { and } surrounding some scripts are meant to avoid cluttering your shell history with individual commands, etc. You can ignore them if you manually copy paste the individual commands.

This guide walks you through creating a high-performance Windows 11 virtual machine (VM) on Fedora Silverblue using GPU passthrough technology. This setup allows you to run Windows applications that require dedicated graphics performance while keeping your primary system secure with Fedora Silverblue.

GPU passthrough allows your virtual machine to use your dedicated graphics card directly, providing near-native gaming and graphics performance in Windows while running on Linux. This is different from typical virtualization where graphics performance is limited.

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Verified Spec-Driven Development (VSDD) is a unified software engineering methodology that fuses three proven paradigms into a single AI-orchestrated pipeline:

• Spec-Driven Development (SDD): Define the contract before writing a single line of implementation. Specs are the source of truth.
• Test-Driven Development (TDD): Tests are written before code. Red → Green → Refactor. No code exists without a failing test that demanded it.

If you often connect to your Linux server using VSCode, the "~/.vscode-server/" folder (and sometimes the ~/.cache/ folder too) can get very large because VSCode:

1. Does NOT clean its download cache after installing extensions;
2. Does NOT delete old extensions after updating them;
3. Does NOT remove old VSCode servers after installing a new version.

If your server storage space is limited, you might consider cleaning "~/.vscode-server/" (and ~/.cache/) regularly using the bash script I wrote. Simply run the following command:

curl -sL https://gist.githubusercontent.com/XDflight/5f3509eb84fc282b88059c909036f5bc/raw/fe2a3e7dab19160c17efc7025d138f5350964c0f/clean_vscode-server.sh | bash -s

• For bookmark queries term is searched within bookmark names and tags. Title is returned if it contains term, tag is returned if only it matches term completely.

This is mostly for my own benefit when I invariably format a computer using these adapters and forget how to get wifi working again:

• TP-Link T2U Nano (AC600)¹
• TP-Link T3U Plus (AC1300)¹

Plug device in and ensure it is detected via lsusb:

For the T3U Plus, the ID is 2357:0138.
